Use the area on the last page to make a paracer trap. Attack him with crossbow tranqs only once. You need 8 extra wooden walls. Stone works too. Thatch is too weak. Put them on the holes and tranq him away. once knocked out break a fence and feed. Works extremely well,if you can get him in!
The only dino that'll agro an unconscious paracer is a Rex. So if those are taken care off and your cautious about not bringing in extra friend with you. You don't have to worry about other creature damaging your tame.
